This project allows you to read many common EPROM and Flash memory chips. It's equipped with USB interface that uses FTDI USB to serial chip. The PIC18F4550 microcontroller firmware handles the various differences of the range of EPROM chips. The project only uses HyperTerminal PC software to control and read the chips. Intel hex and raw binary formats can be sent unencapsulated or by Y-Modem.Kevin Timmerman, project designer, said that there are no jumpers required for configuration. Power can be supplied on the appropriate pin by three 2N4403 transistors. A ...

The Laser Position Sensor (LPS) module is an optical sensor that measures and provides the two-dimensional coordinates of visible red laser light (630-694nm) shined onto its surface. This Freescale MC9S08JM8CLC MCU-based project developed by Joe Grand based on Roger Johnson and Chris Lentz’s 2-D Optical Position Sensor.The Laser Position Sensor has a resolution of 0.0001", an accuracy of 0.001", and a measurement range of +/-0.2" (+/-5mm). It can be used for remote device control, data communications, high-speed photography, long-range beam-break/security trip wires and positioning and alignment. If you want to ...

This Laser Range Finder (LRF) is a low-cost distance measuring instrument that uses laser technology to calculate the distance to a targeted object. It can measure up to 8 feet away but for optimal measurement the range is about 6 inches to 4 feet. The project is designed by Joe Grand.The main parts of Laser Range Finder are Parallax Propeller processor, OmniVision OVM7690 640×480 CMOS CameraCube, and Arima 635nm APC Laser Diode. Distance to a targeted object is calculated by optical triangulation using trigonometry between the centroid of laser light, ...

Audioino is neat way to program an Arduino compatible microcontroller via the audio port of your PC. Chris said to build Audioino, firstly you need to program your Atmega168 with custom audio bootloader. You can use the sketch "ArduinoISP' in the examples folder of the Arduino IDE for flashing or find someone who owns an ISP programmer. And then build your audioino hardware, an Atmega168, 3 resistors, two capacitors, 1 LED, audio jack and a reset switch.To download your Arduino programs to the Audioino, follow this procedures.Develop some programs you ...
